by Eric Rosenbush


TRADITIONAL CATEGORY: sngo sman – wild herbs

TYPES

There are two principal types of spyang tsher, white and black.  The white variety is not a thistle, and has been identified as Morina and Cryptothaladia in various texts. Black spyang tsher can include a variety of thistle genera, notably Cirsium and Carduus.  A further division is also made between stronger, ‘wild’ (rgod pa) and more gentle, ‘tame’ (g.yung) types.

BOTANICAL IDENTIFICATION
Thistles are a large group of thorny plants, classified as the Cynareae tribe within the aster family (Asteraceae).  They are common plants in many areas of the world, both in wild and domestic areas.

 

TASTE AND POTENCY:
Taste: Sweet and astringent taste, sweet post-digestive.
Potency: Classical accounts range between warm and balanced, likely due to regional and species variation.
